Definitions

  • the invention relates to a rotary cylinder lock preferably disposed a door-handle housing of an automotive vehicle which includes a lock cylinder rotatable in a casing with the cylinder being pivotable into closed and open positions of the lock by at least one key associated therewith and insertable in the lock cylinder.
  • the proposed safety mechanisms operate either with acoustic signal or light warning means activated in case of unauthorized use of the vehicle, or operating in such a way that they cut out or interrupt certain functions vital to the operation of the automotive vehicle.
  • This object has been attained by the invention by constructing the rotary cylinder lock in such a way that a second key, a special key, can be inserted in the lock cylinder, this special key exhibiting, at a different location than the main key, notches, projections or the like which control additional locking members and which activates, by pivoting, a switching unit which, if necessary, triggers a safety system so as to prevent unauthorized use of the automobile.
  • the second special key usable for activating the safety system can, in a further development of the invention, be provided, in addition to the aforementioned notches, projections, or the like, with the customary indentations just like the main key so that the car owner or another authorized user need merely use the special key if it is intended to lock the automobile and park the same with the safety system activated. If it is not desired to turn on the safety system, then such person can utilize the customary main key or the duplicate key.
  • the lock cylinder of the rotary cylinder lock can be surrounded by a sleeve which, upon actuation of the lock with the main key, is arrested with respect to a surrounding casing; whereas, the lock cylinder, when activating the lock with the special key, is arrested with respect to the sleeve and, upon pivoting of the special key the lock cylinder and the sleeve surrounding the former are pivoted together, while, in the other case, the lock cylinder alone is pivoted in the lock casing.
  • the rotary cylinder lock can be constructed so that the additional locking members are fashioned in three parts and having such lengths that, when the main key is inserted, the separating or parting lines between the inner and central parts of the additional locking members are disposed in alignment with the parting line between the lock cylinder and the sleeve; whereas when the special key is inserted the separating or parting lines between the outer and central parts of the additional locking members are in alignment with the parting line between the sleeve and the door-handle housing.
  • the lock cylinder can also be constructed so that it can be removed from the door handle only in a displaced functional position attainable solely by the special key. Once this functional position has been activated by the special key, the lock cylinder cannot at all be removed from the door handle, as is also known in connection with the steering wheel lock so that it is impossible for a person to learn, by removing the door handle, something about the form of the special key so as to enable such person to turn the safety system on and off.
  • the lock cylinder for the ignition and steering wheel lock can be fashioned in such a way that additional tumblers are provided in this lock and additional indentations or the like are provided at the keys, which are not present in the other locks.
  • the locking members for the special key are provided in the door lock, it is possible to arrange the tumblers corresponding to the tumblers in the ignition-steering wheel lock so as to make it impossible to determine the structure of the ignition steering wheel lock in the event the lock cylinder is removed from the door.
  • FIGURE of the drawing is a partially schematic cross-sectional view of a rotary cylinder lock arrangement in accordance with the present invention.
  • a rotary cylinder lock is seated in a door-handle housing 1 and has a lock cylinder 2 supported in the housing 1.
  • the lock cylinder 2 is pivotable into the closed and open positions of the lock by means of an inserted key 3.
  • the lock cylinder 2 has the usual tumblers 4 which can be placed, by inserting the associated key, into a position by means of which the lock cylinder 2 and thus also the transmission rod 5 can be pivoted with the pivoting action locking or unlocking the door lock (not shown).
  • the key 3 illustrated in the drawing is constructed as a special key and, in addition to the customary indentations, notches, or the like, it is also provided with special notches 6 adapted to be engaged by inner parts 7a of locking members generally designated by the reference numeral 7.
  • a sleeve 9 surrounds the lock cylinder 2 and the locking members 7 are guided in bores 8 penetrating coaxially the lock cylinder 2, the sleeve 9, and part of the door-handle housing 1.
  • the locking members 7 are urged by the springs 11 in a direction toward a center of the lock cylinder 2.
  • the locking members 7 are divided into three parts 7a, 7b, 7c by way of separating or parting lines.
  • the three-part locking members 7 assume the position shown on the left-hand side of the drawing so that a parting line between the central part 7b and the outer part 7c of the locking members 7 is in alignment with a parting line 12 resulting between the sleeve 9 and the door-handle housing 1.
  • the lock cylinder 2 as well as the sleeve 9 surrounding same are simultaneously pivoted.
  • the sleeve 9 includes an arm 13, which arm is likewise pivoted upon a pivoting of the sleeve 9.
  • the arm 13 is in operative connection with a siwtch 14 with the actuation of the switch causing a safety or warning device (not shown) to be turned on or off.
  • the main key or the second key have no notches at the locations where additional notches 6 are provided in the special key 3, so that the locking members 7, upon the insertion of the normal main or twin key, can only advance up to the smooth places of the second keys as most clearly illustrated in the detailed view designated 15.
  • member 7a can only advance up to a planar place of the normal main or twin key, where no notch is provided.
  • the parting line between the inner locking member 7a and the central locking member 7b arrives at the level of the parting line 16 between the lock cylinder 2 and the sleeve 9 so that now, during a pivoting of the normal main or duplicate key, only the lock cylinder 2 by itself is being pivoted, while the sleeve 9 is prevented from pivoting with respect to the door-handle housing 1 by means of the central locking member 7b.
  • the special key 3 differs from the customary main and duplicate keys only by the additional notches 6, the special key 3 also fits into all cylinders of the remaining locks which fit the normal key and, at those places, the additional notches 6 do not trigger a special function, because no locking members are arranged in the normal locks at the respective locations.
  • the lock cylinder 2 can also be constructed so that it can be removed from the door handle only in a functional position attainable solely by the special key 3 so that it is impossible to gain knowledge about the form of the special key 3 by removing the door handle.
  • the locking members 7 need not necessarily be arranged along the narrow side of the key 3 but can also be operative on the broad side thereof. It is also possible to dispose the special locking members 7 and the corresponding notches 6 at a location where the customary indentations are provided, namely, respectively between such indentations, and in this way, the locking members 7 required for the special function would operate in the same direction as the customary tumblers 4.
